Out of the following given choices;

a) The amount of oxygen produced

b) The rate of ATP synthesis by ATP synthase in the chloroplast

c) The rate at which NADPH is produced

d) The rate at which the protons are transported into the thylakoid

The answer is; A

The photosystem captures energy from sunlight and uses it to split a water molecule.   After splitting the water molecule (by taking an electron), the protein complex transports the electron to plastoquinone. The splitting of water molecules results in evolving of oxygen molecules. The hydrogen is what is used to reduce carbon dioxide to glucose.

The amount of oxygen to be generated will be affected directly.

Further Explanation:

Photosystem is responsible for photosynthetic light reactions of algae, bacteria, and plant.

There are 2 photosystems:

  • Photosystem-1  
  • Photosystem-2

Photosystem-1 plays the main role and utilizes light energy in order to generate high energy carriers such as NADPH as well as ATP. They use p700 photoreceptor and they absorb light of longer wavelength. In this photolysis of water does not occur.

On the contrary, photosystem-2 refers to the protein complex found in the light-dependent reactions of the oxygenic photosynthesis. They present in the thylakoid membrane of the plants, cyanobacteria, and algae. They absorb the shorter wavelength of light. In photosystem 2 photolysis of water occur.

The photosystem absorbs the energy from the sunlight and utilizes it to break the water molecule. After this, the protein complex sends the electron towards the plastoquinone. The breaking of the water molecules leads to the evolution of oxygen molecules. The water is what is utilized to lower the carbon dioxide to a glucose molecule.

Identify and describe the various satellites the orbit in our solar system.
Hitman42 [59]

Answer:

Explanation:

The seven largest natural satellites in the solar system (over 2,500 km in diameter) are the four Jovian Galilean moons - Ganymede, Callisto, Io, and Europa - Saturn's moon Titan, Earth's own Moon, and the satellite captured natural of Neptune Triton.

They move around a larger body. They revolve around these bodies because of their gravitational pull. The orbits that they describe when turning on these bodies can be regular or irregular.

Natural satellites of planets in the Solar System

Mercury → 0.

Venus → 0.

Earth → 1.

Mars → 2.

Jupiter → 79.

Saturn → 82.

Uranus → 27.

Neptune → 14.

Answer:

The correct answer is C- I will need an infusion of this medication once weekly.

Explanation:

Mitoxantrone is a anti cancer drug which is given to stop the growth and spread of cancer. It is infused in patients very slowly taking up to three to five minutes and administered once in every three months for 2 to 3 three years.

Liver functioning Tests and a pregnancy test should be done before each infusion.

Which of the following statements about viral structure is true?
nadya68 [22]

In a viral structure, the capsomere is made up of small protein subunit called capsid. The correct option is b.

<h3>What is capsid?</h3>

Viral capsids are nanometer-sized canisters with complex mechanical characteristics that encapsulate the viral genome inside one host, transit it, and then release it inside another host cell.

Capsids are small protein subunits that make up the b. All viruses contain DNA as their genetic material. Glycoproteins aid virus attachment to the host cell.

Thus, the correct option is b.

Calculate the acceleration of a ball has been dropped from the roof. It accelerates from 10 m/s to 30 m/s in 2 sec. 1 point 15 m
Andre45 [30]

Answer:

10 m/s/s or m/s²

Explanation:

Acceleration can be calculated by using the formula;

a = v - u/t

Where;

a = acceleration (m/s²)

v = final velocity (m/s)

u = initial velocity (m/s)

t = time (s)

In other terms, acceleration (a) can be represented as ∆V/t.

According to this question, a ball accelerates from 10 m/s (u) to 30 m/s (v) in 2 seconds. Hence, the acceleration of the ball is as follows:

a = 30 - 10/2

a = 20/2

a = 10m/s².
